“…These endophytes, because of intimate contact with their host plants, play vital roles in plant development, growth, and fitness, as well as decontaminating polluted soil [13,14]. Endophytic microorganisms are a highly varied group that stay within the tissues of plants for at least part of their life cycle [15]. Endophytic bacteria and fungi host a large amount of genes that degrade pollutants [16].…”

Total petroleum hydrocarbons (TPHs) are a persistent environmental organic contaminant. The possibility of obtaining synergistic effects between plants and microorganisms has further increased the possibility of alternative techniques for bioremediation. Oloptum miliaceum (L.) Röser & H.R. Hamasha and Pennisetum setaceum (Forssk.) Chiov. are, undoubtedly, good model plants for phytoremediation because they have large roots, leaf biomass, and a fast and effective renewal capacity, also, they have a great capacity to host endophytes in their roots. Gas chromatography-mass spectrometry (GC-MS) based on carbon fraction number was a basic technique used to determine the hydrocarbon degradation, and microorganism’s population was identified by high-throughput sequencing of 16s rRNA. The microbial consortium used allows the plant to increase overall biomass, adapt more in terms of redox biology (Superoxide dismutase SOD, catalase CAT, ascorbate peroxidase APX, guaiacol peroxidase GPX), and stress markers (Glutathione S-transferase GST, Phenylalanine Ammonia Lyase PAL, Proline content, and lipid peroxidation MDA). In addition, the photosynthetic efficiency and the soil dehydrogenase activity were monitored. After 240 days, the percentage of TPHs removed in Group 2 was 94%, whereas in Group 1, it was 78% in Oloptum miliaceum and Pennisetum setaceum. The removal of aliphatic hydrocarbons (C13–C36) was observed in Oloptum miliaceum and Pennisetum setaceum inoculated with the consortium of indigenous bacteria selected from rhizosphere soil and mycorrhizae strains. Our data demonstrate that, the Poaceae, in relation to its great ecological and vegetative potential, could be a great candidate for extensive remediation of soils contaminated by TPHs.

“…Bacterial endophytes initially stick to the root surface and explore the potential entry sites to access the internal plant tissues. Opening in the roots, where root hairs or lateral roots emerge, as well as wounds in the shoots, are considered the main entry points that endophytes use to enter the host plant and access its internal tissues (Mercado-Blanco and Prieto, 2012;Compant et al, 2016;Kandel et al, 2017). Therein, they reside for most of their life with no detrimental impact to the host plant (Mercado-Blanco and Lugtenberg, 2014;Hardoim et al, 2015).…”

Summary Several important bacterial characteristics, such as biological nitrogen fixation, phosphate solubilization, 1‐aminocyclopropane‐1‐carboxylate deaminase activity and production of siderophores and phytohormones, can be assessed as plant growth promotion traits. Our aim was to evaluate the effects of nitrogen fixing and indole‐3‐acetic acid (IAA) producing endophytes in two Oryza sativa cultivars (Baldo and Vialone Nano). Three bacteria, Herbaspirillum huttiense RCA24, Enterobacter asburiae RCA23 and Staphylococcus sp. 377, producing different IAA levels, were tested for their ability to enhance nifH gene expression and nitrogenase activity in Enterobacter cloacae RCA25. Results showed that H. huttiense RCA24 performed best. Improvement in nitrogen fixation and changes in physiological parameters such as chlorophyll, nitrogen content and shoot dry weight were observed for plants co‐inoculated with strains RCA25 and RCA24 in a 10:1 ratio. Based on confocal laser scanning microscopy analysis, strain RCA24 was the best colonizer of the root interior and the only IAA producer located in the same root niche occupied by RCA25 cells. This work shows that the choice of a bio‐inoculum having the right composition is one of the key aspects to be considered for the inoculation of a specific host plant cultivar with microbial consortia.

“…Seeds can facilitate the dispersal of microorganisms, providing for early colonization of a new plant generation. Although seeds are an important means of supporting microbial growth and dispersal, relatively little is known about the ecology of seed-associated microorganisms (Saikkonen et al 1998;Compant et al 2010;Truyens et al 2015;Brader et al 2017) in comparison with root-and leaf-associated microorganisms (Mercado-Blanco and Lugtenberg 2014;MercadoBlanco 2015;Vacher et al 2016;Compant et al 2016). In many instances, the composition and structure of the seed microbiota of various plants species have yet to be characterized.…”
